Boundary Layer Microphones
Installation
1. Please refer to Fig. 3 and identify the parts shown.
2. Determine where you want to install the microphone, and drill a 25/32-inch diameter hole
there.
3.
PZM-10 only:
Obtain some 2-conductor shielded mic cable, long enough to run from your
equipment input to the microphone. If space is tight behind the mounting surface, obtain a
right-angle female XLR connector. Solder the female XLR connector onto the cable: shield to
pin 1, hot lead to pin 2, other lead to pin 3.
PZM-10LL only:
Obtain enough mic cable to run from your equipment input to the
microphone. You can use either a 2-conductor shielded mic cable with a separate DC power
lead, or a 3-conductor shielded mic cable (with one of the leads used for power).
4. Run the female XLR (if used) and mic cable to the hole.
5. Using a 5/32-in. Allen wrench, remove the collar from the microphone. Insert the
microphone tube into the hole.
6. Slide the collar onto the mic tube. Pull the plate tight against the hole and press the collar
tight against the mounting surface. Tighten the Allen screw in the collar.
7.
PZM-10 only:
Plug your mic cable into the microphone.
PZM-10LL only:
Solder the PZM-10LL cable leads to your mic cable as described below:
Red to 12-24V DC
White to Audio + lead
Black to Audio – lead
Shield to cable shield and power supply
To pick up speech from a small conference table (about 6 feet square), mount the PZM-10 or
PZM-10LL in the middle of the table. For longer tables, use one PZM in the middle
of every 4 to 6 people. No person should be more than 3 feet from the nearest microphone.
Architects’ and Engineers’ Specifications
The microphone shall be the Crown Model PCC-130SW or equivalent. The microphone shall
be a half-supercardioid electret condenser type. The microphone shall employ the principle of
phase coherency achieved by mounting a small-diameter element very near a boundary, thus
eliminating comb filtering in the audible spectrum.
The microphone will exhibit excellent off-axis response and gain-before-feedback. A 4,6 m
(15 ft.), two-conductor shielded cable with XLR connectors shall be supplied with the
microphone.
The PCC
®
-130SW shall have a silent operating membrane switch which can be configured
for push on/off, momentary on or momentary off operation.
The PCC
®
-130SW is specified.
